Okay here is my dilemma.....I bought 24 fertilized eggs. Today is day 14 of them being in the incubator. I had placed 5 under my broody hen but they all have gone bad but 1. I placed the 1 in the incubator which showed lots of veins and development initially. I have a friend who wants to check the fertility of hers so I added those to the incubator as well....only 2. My broody has given up on the nest she was in I guess she knew those eggs were not developing. She is now laying on all the others eggs (they all lay their eggs in the same box) and all of those are infertile! Can I place eggs that have in the incubator under her to lay on until they hatch only 3 of the 24 are developing? Should I place the newest or most developed under her? Believe it or not I am talking about a broody white leghorn (1st time brooder) only 7 months old but, very determined to be a Momma!!! Any info/advise is helpful. Thanks. I will post a pic of her.
